Alexandrite is one of the rarest of all colored gemstones and is famed for its color change from green in daylight to red under incandescent light. Fine faceted alexandrite over 1 carat is more valuable than sapphire, ruby or emerald.
Alexandrite is a variety of chrysoberyl, with an excellent hardness of 8.5 on the Mohs scale, placing it right behind sapphire and ruby. Alexandrite is rare because of its chemical composition. Chrysoberyl is colored by traces iron and titanium, but alexandrite is also colored by chromium, which gives it the emerald green hue in daylight.
I have known about GemSelect for a while but this is my first purchase because I am a jewelry maker in the market for lower-priced gems that I can resell in jewelry. It's difficult to make much of a profit on cheaper jewelry when the shipping price is sometimes half of the total cost of the stone. I would make more purchases if I was in the market for a lot of higher-priced gems, but for now it will be just every once in a while that I shop here.
That being said, I think that the prices for gems are fair and I will continue shopping with GemSelect for my higher-priced gems that I make for myself or for orders that want specific gems that I can only find here.
